IUD's

Background

The IUD is a plastic, t-shaped device that is inserted into the uterus. It prevents fertilization of the egg. There are two types used in the US currently, ParaGard IUD (nonhormonal) and Mirena IUD (hormonal--contains progestin). The ParaGard will be effective for 12 years, while the Mirena will be effective for about 5 years.

Advantages

Both are effective and safe (usually recommended for women who have already had a child).

Both are long lasting, neither contain estrogen.

Not prohibitively expensive.

Does not affect sex.

Mirena brand has been known to decrease menstrual bleeding.

Disadvantages

ParaGard may cause heavier and longer bleeding, may lead to more cramps.

Insertion can be painful, may cause early bleeding.

Does not protect against STIs.

Some women expel their IUD.

Efficacy

The chances of conception for both types of IUDs are less that 1%.
